To all whom it may concern:

Be it known that we, EDWARD Gr. Bonn and CHARLES A. Connii, both citizens of the United States, and both residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Car Seats, (Case 13,) of which the following is a specification.

The object of the present invention is to provide a simple, durable and efficient mech anism for connection with the reversible or otherwise movable back of a seat of the type used, for instance, in railway cars.

A further object is to provide mechanism of the character stated which, while possessing maximum strength, shall be compact and capable of being so protected as to avoid the danger of the catching of clothing in the moving parts thereof.

A further object is to provide a mechanism which may readily be adapted for use in one of several types of seats, as, for in stance, that type of reversible seats employed in cars having central aisles and access to which seats is had through such aisles, or that type of similarly reversible seats commonly employed in summer cars, access to which is had from the sides of such cars.

In carrying out the invention, we employ either a movable or stationary seat of any suitable construction, and a back movable from one to the other longitudinal edge of such seat. Said back is supported by arms pivoted thereto, or to an appurtenance thereof, and to a suitable part adjacent to the seat, as, for instance, to the seat-frame, or a post adjacent to such seat-frame, and these arms are so correlated at their point of attachment to such frame or post as to assure smooth and uniform movement of the back from one facing direction to the other. In practice, said arms are preferably curved so as to permit a back of less width than the seat to be employed, thereby not only reducing the weight of the back but also increasing the space between the back of one seat and the forward edge of the next adjacent seat in the rear at the seat ends. Additionally,

said arms are preferably made of curved or angular cross-section, thereby desirably contributing the element of strength and making it possible to use lighter material in such arms than would otherwise be essential.

lhe invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a seat adapted for use in a summer car; Fig. 2 is an elevation of a portion of such seat, the parts being broken away to disclose the details of construction thereof, and the back being shown in its intermediate position between its two facing directions; and Fig. 3 is a plan view of the structure shown in Fig. 1, the seat proper being omitted and the car post to which part of the mechanism is secured being shown in full lines.

In describing the invention in detail, we shall refer to the mechanism at but one end of the seat, it being understood that such mechanism may be duplicated at the other end or such other means employed as to adequately support and guide the seat-back under the influence of the mechanism described in detail, in its movement from one facing direction to the other.

Referring to these drawings, A designates one of the side posts or standards of a summer, convertible or semi-convertible car, and extending between such posts and a central aisle or the corresponding post on the other side of the car, is a seat B, here shown as stationary (although it may be shiftable), such seat having preferably the rounded ends 2 G designates a reversible seat-back, here shown as provided with an end-plate 0 detachably secured to said back. Said back C or the end-plate c secured thereto may be provided with a buffer 0 of rubber, leather or suitable material, for contact with the seat B to limit the movement of said back.

D, E, designate respectively upper and lower back-supporting arms, one or both thereof being of curved or angular crosssection, as illustrated in Figs. 2 and 3 in side view and in Fig. l in section, and said arms are, as shown in said Figs. 2 and 3, curved intermediate of their ends and provided at their outer ends with pivot-plates or flanges d, e, through which pass the trunnions or pivots cl, 6, presently to be described.

The end-plate a is, as shown in Figs. 2 and 3, angular in cross-section, comprising the webs 0 0 the former web coacting with the end of the seat-back C and the latter with one of the faces of said back. sired, however, said end-plate may be U- shaped in cross-section, the central web coacting with the end of the back and the outwardly extending parallel webs with opposite faces of said back.

a designates a bearing-plate, preferably countersunk into the end of the seat-back and lying parallel with the web 0 of the end-plate a. Each of the trunnions cl, 6 comprises the enlarged portion 0 located in a recess in the seat-end, the reduced portion 0 movable relatively to the bearingplate 0 and upon which said plate and the back to which it is secured are adapted to swing, and the head 0 extending through and expanded outwardly upon the coacting flange of one of the back-arms above described. Preferably both of the pivots or trunnions (Z and 0 will be the same in construction, ample strength being contributed thereby.-

F designates a metallic pivot-plate, preferably formed of stamped or pressed steel and paneled, if desired, for greater strength, as shown in Fig. 2.

G designates a metallic cover-plate lying parallel with the pivot-plate i both said plates being parallel and in ciose proximity to the post A. Extending between and connecting said plates are pivots 0r trunnions f, f, and f Each of said pivots or trunnions f, f, comprises a central enlarged portion f and a reduced portion on either side thereof, each of such reduced portions coacting with a suitable orifice in one or the other of the plates F, G. Upon the enlarged portion f 'of the pivot or trunnion f, is mounted the inner end of the back-supporting arm D. The end of said arm is formed into a segmental rack H, and with the teeth of said segmental rack coact corresponding teeth carried by the pinion I. Coacting also with the teeth upon said pinion I, are the teeth of another segmental rack J, mounted upon the central enlarged portion of the pivot or trunnion f said pivot or trunnion extending through the cover-plate G and being secured, as shown at 7', to the inner end of the lower back-supporting arm E.

It will thus be seen that the back-supporting arms D, E, are necessarily interrelated in their movement between the two extreme positions of the seat-back C, such interrela tion being due to the coact-ion of the pinion I and the segmental racks H and J. It will If S191 thereof also be seen that the moving parts, other than the back and those port-ions of the arms distant from said pinion and racks, are adequately housed and protected bythe coverplate G. Said cover-plate is preferably provided with angular flanges g, 9', extending the edges but not to sufiicient height to interfere with the freedom of operation of the arm D. Said cover-plate G nd said bearing-plate F may be secured to the post A in any suitable manner, as, for instance, by bolts or screws 9 The construction above described offers many and. important advantages; among them are that adequate strength and durability are secured, ease and uniformity of movement of the back from one facingdirection to the other are obtained, the contheir outer ends thereto, two plates secured together parallel to but spaced apart from each other and having flanges at their lateral edges for closing the space between the plates, one of said arms having its inner end extending between and pivotally con- 7 nected to said plates and provided with a rack, and the second of said arms having its inner end lying adjacent to the outer side of one of said plates, a pinion pivotally mounted between said plates and meshing with said rack, a second rack pivotally mounted between said plates and meshing with said pinion, and means for connecting said second rack with the inner end of said second arm, substantially as set forth.

2. In a seat, the combination of a reversible back, a plate, back-supporting arms pivoted at their outer ends to said back, pivotpins for pivotally supporting the inner ends of said arms upon said plate, segmental racks carried by the inner ends of said arms, a pinion meshing with said racks, a second plate secured parallel and close to the first-named plate by said pivot-pins, said plates closely inclosing the racks and pinion, and a flange on one of said plates serving to inclose said gearing at the edges thereof but cut away to permit free movement of one of said arms in reversing said back, substantially as set forth.

3. In a seat, the combination with a rel versible back, of a plate secured to the edge thereof and flanged longitudinally, a bearing-plate between the plate first named and the edge of said back, and curved back-supporting arms pivoted at their inner ends 3 to a permanent part of the structure and at their outer ends to said flanged plate and said bearing-plate, substantially as set forth. 1
